A 21-year-old Florida man facing sexual assault and battery charges penned apologetic letters to two of his alleged victims, providing confessions that will likely be held against him by prosecutors.

Josh Sekulic, a junior at Florida Gulf Coast University, was arrested Monday after two fellow students told campus officers that they were raped by him, and a third said he physically assaulted her, NBC 2 in Fort Myers reported.

Two of the victims, the first and third, recounted similar stories to campus police. They said the attacks took place in their respective residences and on both occasions, Sekulic demanded sex, then raped the women twice after they said no.

According to a police report, Sekulic admitted to another sexual assault while raping one of his victims. One of the victims told police that Sekulic said: "You are completely emotionless and this is how sex will be for the rest of your life. I've (expletive and identifying reference deleted) with the lights off, because she is the exact same way, emotionless,” and “I have to do this.”

Another woman said Sekulic was hanging out in her student apartment when he began fooling around with her iPad. When she asked him to leave, he allegedly bit her and pinned her down on her bed. She told officers that she was eventually able to get free and Sekulic left.

All three of the alleged attacks involved female students at FGCU and took place within six days in late October.

In letters obtained by CBS affiliate WINK News in Fort Myers, Sekulic wrote to several women he’s accused of assaulting the same day as his arrest on Monday and confessed to the crimes, saying he was sorry for his “mistake” and hoped his apology would help them move on.

His one-page letters to the women included the explanations: "You invited me over, I took that as a sign that you wanted to have sex," "I did not think that you wanted me to stop and I kept going,” "What transpired that night was a mistake" and “I hope this apology helps you somewhat and I wish you the best."

Sekulic is currently being held at the Lee County Jail with bail set at $225,000. The judge who presided over his court appearance on Tuesday morning ordered him not to have any contact with the women. University officials said he is currently prohibited from appearing on campus and members of the fraternity and rugby team he belonged to said they had severed ties with him.
